1 - Searching the Map

Selecting the magnifying glass icon will open search bar that will function just like Google maps.

Example 1 - Victorville, CA

 


Example 2 - Hemet, CA

 


2 - Toggling Map Layers

With the Layer Control menu you can turn on & off certain layers of the map to customize the viewing experience. In this example we toggle the Zip Code layer.


3 - Zoom Controls

Selecting the \(+\) sign will zoom the map in to see a narrower view

Selecting the \(-\) sign will zoom the map out to see a wider view

Alternatively you can use your mouse scroll wheel to achieve the same results.

4 - Resetting the Map View

After altering the map view in any way to quickly reset the map select the push pin icon.

With the Panning Tool we can freely move the map around to view different areas of the map.

Rectangular Selection

The rectangular selection tool allows us to select large areas very quickly.

Radial Selection

The Radial Selection tool allows us create a circular selection region, this is great for determining how far patients live from a specific clinic.

In this example lets see how many patients live within a \(10\) mile radius of our Barstow clinic

 


Lasso Selection

In instances where the rectangular or radial selection is not precise enough consider using the Lasso selection tool to draw a custom region.
